1 General
This user’s guide is meant for the installer and for the end user. It’s a reference to operation and
installation of an ACM air curtain. For safety sake and to guarantee correct operation, it is essential
that you read this manual thoroughly before starting the installation, including all tips and warnings.
Keep this manual with the appliance and see to it that it is included when the appliance is moved or
sold, to ensure that everyone is informed about the use and safety aspects of the device throughout its
lifetime.
1.1 Description
The Air Curtain Module consists of a metal casing with a bladed fan and motor on top, secured by a
fan guard. There is a discharge nozzle with louvers on the opposite side, which enables the airflow to
be directed in the desired direction. An air curtain consist of multiple Air Curtain Modules with an
assembly set.
1.2 Function
The air curtain functions as an invisible door/segregation and has insulation properties, this can
reduce energy losses up to 80% with an open door. The air curtain can be used with chilled or heated
spaces. In most circumstances an air curtain is used to minimise heat losses with an open door, it
could also be used as a segregation between a non or limited heated space and warmer heated
space. For example between a storage space and workshop.
The airspeed can be controlled by an optional 5 stage speed controller, which can be used to adjust
airspeed for different heights (widths), difference in forced ventilation (negative pressure) within the
building or for variation in weather influences. The switch has a stage that cuts off power to the
installation. (stage 0).
The air curtain can be activated through the use of a door switch, which triggers a relay which in turn
sends the power to the air curtain.
1.3 Warranty
Operation/installation of appliances not according to this manual will void the warranty. It’s not allowed
to change the specifications or to make modifications of any kind, on this appliance.

2 Technical data
2.1 Table with data
Because the ACM air curtain consist of multiple modular sections, a variation of different widths or
heights (vertical installation) can be constructed. Theoretical there isn’t a limit to the amount of coupled
modules, but every 10 connected modules must be succoured/supported at each end.
If more than 10 modules are used there needs to be a another power source, because the internal
wiring is designed for a maximum amperage of 10A.

2 .2 Pre-check
Before installation, please check (i.e. on the data badge) if the appliance is in accordance with the
order and whether it suites the local and present provisions ( electrical supply etc.)
Also check after installation that operation of the appliance can’t form any hazard caused by moisture
and dust, or can cause injuries to people.

3 Installation
3.1 Suspension
Every unit has 4 popnuts at each corner, in the illustration on page 4 the dimensions are depicted with
the notification H-H. By using these popnuts one can mount the air curtain to the wall or ceiling with
our consoles or M10 studs. These are not included (as standard). The coupled modules have to be
suspended or supported at each end. The maximum non supported or suspended coupled units is set
at 10 modules (5m) to prevent sagging.
3.2 Calculating number of modules
Each module is 500mm long. One can find the number of modules with resulting length in table under
§2.1. The air curtain has to be wider than the door opening, to accomplish as good as possible
segregation.
Calculation : Measure the width of the door in cm and divide with 50, the resulting number is the
minimal number of modules. Almost always there is an extra module needed for enough overlay.
3.3 Positioning
Make sure the air curtain has undisrupted flow of intake air and blown air, there should be a minimum
distance of 0.5meter between ceiling or overhead door. Horizontal mounting is preferred above vertical
mounting, because that way the air curtain will also serve as a recirculation fan and the air stream will
be warmer than on floor level. The side of the air stream should be as close as possible to the edge of
the door opening, the further the air curtain is placed away from the door opening the less effective it
becomes. The distance to the wall w.ith our horizontal console is variable between 41-368mm, with
the vertical console this is between 0-300mm. The maximum mounting height is 4,5meter. In case of
vertical mounting the maximum door width for one air curtain is 4,5meter. For other dimensions ask
your reseller for advice. With use of the adjustable louvres, one can change the direction of the air
stream, the louvres may not be set at extreme angles, because this has a negative effect on the
efficiency of the fans.

4 Electrical connection
Warning:
Before starting installation make sure that that electrical group you are working on, has been shut off.
The appliance should have earth!
4.1 230Vac supply
The installation must comply with all applicable local and/or national standards i.e. NEN 1010.
There should be a suitable electrical group with a main fuse. There is an electrical diagram further on
in this guide.
The supply is 230Vac (50 Hz) with earth.
4.1.2 Isolation switch or power plug
The appliance has to be equipped with a 230 Volt isolation switch or power plug. This switch should
be suitable for the maximum accumulated amperage. This switch should disconnect phase and neutral
(not earth) and have at least an 3mm contact opening. Switches or power plugs must be accessible at
all times.
For power supply the unit has been provided with a 3-pole power plug (female). The installer should
connect a 3-wire mains cable and a power plug to it.
4.2 Connection options
4.2.1. Connection without speed control
With the interference of an isolation switch or power plug the air curtain can be connected to the
mains. If the connection is made the fans will run continually at full speed.
See chapter 6.2
4.2.2. Connection with door switch
The air curtain can be activated as the door opens. This can be done with the use of a door switch,
which powers the relay of the relay box (article GA4100) and activates the air curtain.
See chapter 6.3
4.2.3. Connection with speed control.
The airspeed can be adjusted with the 5-step switch for different heights (widths), difference in forced
ventilation (negative pressure) within the building or for variation in weather influences. Step 0 can be
used to shut off the power.
Function:
The 5-stage speed control is installed in between the power source. Depending on the chosen stage,
the fan will turn fast or slowly. Before installation consult the manual of the 5-stages switch.
See chapter 6.2 and 6.3

5 Setting, operation and maintenance
Warning:
Before starting maintenance make sure that the power group you are working on has been shut off!
The appliance should have earth!
5.1 Operation
With the 5-step switch one can adjust the airspeed on ground level, as explained in §4.2. The airspeed
on ground level may not be too low because the air curtain can’t withstand any wind load. Too high
airspeed at ground level will lead to on-necessary turbulence and excessive sound. The ideal flow
profile is depicted in the illustration beneath, one can roughly check this by feeling with the hands, or
tuft testing with a string of paper to visualise the airflow profile. But off course an anemometer would
be best. If there is a strong wind load on the door opening, one can turn up the airspeed. The air
curtain isolates the interior space, thus it can be used in summer. Not only to repel the heat , but also
to wear off flying insects who avoid higher airspeed than there surroundings.
Attention: do not set the louvers in an (sloping) angle bigger than 20°. This will decrease the air
output.

5.2 Maintenance
In spaces with heavy dust it might be necessary to clean the fan guard with compressed air once a
year. If the fan guard is covered with severe dust the fan will have diminished suction capabilities.
